[FEATURE] Add the option to allow the app in the background

[JetPlane340]

Is your feature request related to a problem? Please describe.
When changing the notch settings, I quit the app because I’m used to the shortcut to quit apps.

Describe the solution you'd like
If the app can run in the background, it won’t quit when using the shortcut to close the settings tab.

Additional context
This could also improve the apps reliability.
